This is a part of an static int method:
int answer = 0;
foreach(int getal in savedNumbers)
{
Console.WriteLine(getal);
answer = answer + getal;
savedNumbers.Clear(); // after this line, I'm getting an error.
}
return answer;
Please help me … I don’t know why savedNumbers.Clear() isn’t working at that line.
EDIT: Thanks, problem is solved.
You can't modify the collection while enumerating over it. So, the exception is valid. Clear once you are done with enumerating it.
